About SAN Extensions
12 Continuous Access and Data Replication Manager SAN Extensions Reference Guide
Figure 1: Types of SAN extensions
A SAN extension can be used with any Fibre Channel topology. Much of the
extension testing performed by HP on third-party vendor equipment was done in
environments running replication between extended SANs.
Four HP replication solutions are discussed in subsequent chapters. These
solutions make use of Fibre Channel technology but differ in the storage
architecture used. Data Replication Manager makes use of the HSG80 controller
and Array Controller Software (ACS) V8.6P, V8.7P, or V8.8P to provide
disaster-tolerant data. HP StorageWorks Continuous Access EVA with the
EVA4000/6000/8000 uses Xcelerated Controller Software (XCS) V5.0 or later.
HP StorageWorks Continuous Access EVA with the EVA3000/5000 uses Virtual
Controller Software (VCS) V3.0 or later. HP StorageWorks Continuous Access
XP provides XP controller-based, long distance disaster tolerance copies of your
data.
Note: EVA4000/6000/8000 storage systems are currently only supported with
Continuous Access EVA SAN Extension using WDM.
